一.前言若一线性数字网络包含P个乘子,它们的系数分别为a_1,a_2……a_p,并且分别接在节点j_1与K_1,j_2与K_2,……,j_p与K_2之间。本文论述部分或全部系数a_i变化△a_i时传递函数T_(ab)(Z)(?)W_b(Z)/X_a(Z)中变化的计算方法(W_b——节点b处的输出变数;X_a——节点a处的输入电源变数)。假定△a_1较大,以致一阶关系式△T_(ab)(?)sum from j=1 to p((?)T_(ab)/(?)a_i)△a_i已不再足够准确。
I. Introduction If a linear digital network contains P multipliers, their coefficients are respectively a_1, a_2 ... a_p and are respectively connected between nodes j_1 and k_1, j_2 and k_2, ..., j_p and k_2. This paper discusses the calculation method of the change in the transfer function T_ (ab) (Z) (?) W_b (Z) / X_a (Z) when some or all of the coefficients a_i vary by Δa_i (W_b - the output variables at the node b; - input power variable at node a). Assuming that Δa_1 is large, the first-order relation ΔT_ (ab) (?) Sum from j = 1 to p ((?) T_ (ab) / (?) A_i) Δa_i is no longer accurate enough.
